Do you know Dr M.S. Swaminathan? He is known as the “Father of the Green Revolution in India” for his work in improving agricultural productivity in India. Dr JC Bose, a pioneer in biology, proved that plants are alive just like us. There are several such examples. If you want to be like them, this blog is for you.
A biologist is a scientist who studies living organisms and their interactions with the environment. Biologists may specialise in ecology, genetics, physiology, microbiology, biochemistry, etc. They advance scientific knowledge, develop sustainable food systems, protect the environment, and contribute to technological advancements. Biologists are critical in finding solutions to some of our most pressing challenges. The recent pandemic provides the best examples.
In this blog, we will cover the following:

How do biologists differ from Doctors?
A biologist is like a nature detective who studies plants, animals, and other living things to determine how they work and interact with their environment. They might research anything from how cells grow and divide to how different species of animals live together in the wild. Biologists might work in labs, go to the field to collect data or teach others about biology.
On the other hand, a doctor is like a superhero who helps people stay healthy and fight off sickness. They’re experts in the human body and how it works, and they use this knowledge to diagnose and treat all kinds of illnesses and injuries. Doctors typically work in hospitals, clinics, or private practices, interacting with patients and other healthcare professionals. They may diagnose and treat medical conditions, prescribe medications, perform surgeries, and provide preventative care. If you want to be a doctor in India, check out this blog.
What does a biologist do?
A biologist’s work is diverse and multi-faceted, encompassing many areas of study and research. Whether working in a laboratory, field, or classroom, biologists are essential in advancing our understanding of the natural world and promoting conservation and environmental protection.
To be successful in their work, biologists must have a deep understanding of the scientific method and research techniques, as well as a strong foundation in biology and related fields. They must be skilled in data analysis and interpretation and have strong critical thinking and problem-solving abilities. They must also communicate their findings and ideas effectively in writing and presentations.
Here are a few aspects of their work:
Research (and Academia):-
One key aspect of a biologist’s work is research. Biologists may work in laboratories or out in the field, studying organisms and their behaviours to understand their biology better. They may collect samples, analyse data, and conduct experiments to investigate topics such as genetics, virology, ecology, or evolutionary biology.
In addition to research, biologists may also be involved in teaching and education. They may work as professors, teaching students about biology at the high school, undergraduate, or graduate levels. They may also develop and design curricula, create educational materials, and mentor students in their research.
Another critical aspect of a biologist’s work is conservation and environmental protection. Biologists may work for government agencies or non-profit organisations, developing and implementing policies to protect and preserve endangered species and ecosystems. They may also work to address environmental issues such as pollution or climate change, studying the impact of human activity on the natural world and developing solutions to mitigate these impacts.
Dr Madhav Gadgil, an ecologist and environmental activist, has worked to promote sustainable development in India and advocated for protecting India’s natural resources, particularly its forests and biodiversity.
Biologists may also be involved in scientific outreach and communication, working to educate the public about the importance of biology and the natural world. They may write popular science books, create educational videos or podcasts, or participate in community outreach events to share their research and knowledge with the public.
Types of Biologists:
There are several types of biologists, each with its own area of specialisation and focus. Here are some of the most common types of biologists:
- Microbiologists: Microbiologists study microorganisms, such as bacteria, viruses, and fungi. They investigate their structure, function, behaviour, and interactions with other organisms and the environment. Microbiologists work in various settings, including research labs, hospitals, and public health agencies.
- Molecular biologists: Molecular biologists study the structure and function of molecules within cells, including DNA, RNA, and proteins. They use techniques such as gene editing and recombinant DNA technology to manipulate these molecules and study their effects on cellular processes. Molecular biologists often work in research labs or biotech companies.
- Cell biologists: Cell biologists study the structure and function of cells, including their organelles and other internal systems. They investigate how cells communicate with each other and how they respond to stimuli from the environment. Cell biologists often work in research labs, hospitals, or academic institutions.
- Developmental biologists: Developmental biologists study how organisms grow and develop, from embryonic development to adult form. They investigate how genes and environmental factors influence the development of organisms and how mutations or abnormalities can lead to developmental disorders. Developmental biologists often work in research labs or academic institutions.
- Evolutionary biologists: Evolutionary biologists study how species evolve and change over time. They investigate the mechanisms of natural selection, adaptation, genetic drift, the fossil record, and comparative anatomy. Evolutionary biologists often work in academic institutions or research labs.
- Ecology and environmental biologists: Ecology and environmental biologists study the interactions between organisms and their environment, including ecosystems, populations, and individual organisms. They investigate how human activities, such as climate change and habitat destruction, impact the environment and the organisms that live within it. Ecology and environmental biologists often work in research labs, government agencies, or conservation organisations.
- Biomedical researchers: Biomedical researchers study disease mechanisms and develop new treatments and therapies. They investigate the molecular and cellular basis of diseases and develop drugs, vaccines, and other medical interventions to treat them. Biomedical researchers often work in research labs, hospitals, or biotech companies.
- Wildlife biologists: Wildlife biologists study wild animals’ behaviour, ecology, and conservation. They investigate how animals interact with their environment and with each other and develop strategies to protect and conserve wildlife populations. Wildlife biologists often work in government agencies, research labs, or conservation organisations.
These are just a few examples of the many different types of biologists. Depending on their area of specialisation, biologists may work in various settings, including academic institutions, research labs, government agencies, or non-profit organisations.
